no audioguru,
i think u did not get my question .my question was does our body pick up only 50 Hz or any frequency signal by which it is surrounded say even a 30 Hz or 100Hz .
in other words ,,
is our body an antenna tuned at 50Hz or does it get automatically tuned to any frequency around it? -
hi audioguru ,
thats a strange thing u told.in india we have mains frequency as 50 Hz .Does our body pick only 50 Hz ?
If i am in a country with 30 Hz mains frequency and there i touch a CRO with a fan blowing over me ,what will i get on screen?
30 Hz or nothing?
In other words, is our body tuned to 50 Hz or any mains frequncy noise around us? -
in case your application demands a switch on for some time and off for some time why dont you go for a simple clock type ?
u can control the duty cycle as well as the timpe period as per your need.
any problem with that? -
hi audioguru!
as of what i know till now is that any source can give any current depending on the resistance .what r ur views?
but ofcourse too much current causes it to cross rated power and burns it off!
am i correct?
in short ...are voltage sources current rated or voltage rated? -
indeed 6552 is a regulator .capacitors also r of many types .some are electrolytic (with polarity) while some are ceramic .
resistors also of different makes.
so cant say without seeing them -
it depends on the PC configuration and the manufacturer.Laptos have it on the board itself.
while desktops have it (some ) on their sound cards while some have separate! -
through my college studies /books.
;D -
fermi level is the level of energy where there is a 50% possibility to locate an electron or simply
its the energy which most of` the electrons have .
it depends on doping concentration .... -
what advice do u want ?
i mean whether to set it up or not? -
hi.
how about using a charging RC circuit so that capacitor voltage builds upto 0.7V in 3 mins .this can be fed to the base of a transistor and push it in saturation.
your views ???? -
it has nothing but an RC (charging discharging circuit ) inside
-
hello friends ...
a nice pt to discuss.what happens if we remove the "R"
Between them? -
a fixed voltage divider has 2 resistances in series while a variable voltage divider has a resistance in series with a POT.
-
indeed u can derive ohms law.
it comes basically from charge carriers and mobility definition.
mobility =speed/Electric field..
speed =distance /time and field = Electric field / distance
hence derived .name the constant as R
moreover ur definition of law is not correct.it does not say V=IR but indeed it says
V / I =Constant .... -
audioguru is correct according to me.
as of what i feel the voltage drop is of main concern in any case.
moreover a safety factor of 3 times is more than sufficient. 15-20 A wire for 5 A max current is not at all a bad choice.
what do u say audioguru? -
problem in what sense?
if u are using it as a clock edge generator,its not at all a problem infact good.
what is your application? -
cls is infact clear screen.
there is a file also in your PC where u can specify where u want to be (ur default directory) when u switch to dos.
our frnd has set it to c:\documents\something\something.
u can set it to C:\
or the other method is just described to u.... -
20 ohm?
hey man,i would like to know how u designed it....
internal resistance of a current source is in mega ohms.doesn't it load it?
i know its tough to design a constant current source for low resistance and constant voltage supply for high resistance?????
or is it the other way around??? -
These are special purpose diodes which have small charge storage time which enables them to work at very high(microwave frequencies)
;D -
the circuit you connect to the transformer draws its own current according to its resistance .
but this 15 A which u are talking about is the transformer rating.
2 coils connected in parallel!!!!
god knows what interferences come !
and how much current it drws.moreover always keep a safety factor!
so better run only one M/C on it. -
an alternate path for the current to flow.
more the number of paths ,more free is the flow and hence lesser resistance! -
hi rigdoctor!
how have u built this program?
i mean which language?
i am keen to see it.great work!
can i have it from u?
;D -
only turns ratio and wire thickness determine transformer characteristics and not its size!!!!
-
well not much difference .Vcc refers to BJTs and Vdd and Vss refer to FETs...

digital multimeters are readily available for that purpose!!!!
